Use 'compress catalog after' option in the Windows Admin Console, Host Properties->Master Server Properties->Global NBU Attributes. I set it to 120 days when my disk filled up and it went down to 75% full. It also took less time to backup. I'm going to try 60 days now. I don't get requeststo restore anything past a couple weeks old anyway?

Our catalog backups have always run a little long, but lately it seems to have gotten even worse. Backing up our 83 GB catalog is taking around 6.5 hours now, which comes out to about 3719k/sec. Does anyone have any suggestions for increasing the throughput rate of this backup ? The catalog is cleaned up fairly often so there's not much I can do to shrink its size without altering our retention periods. Only the master server is being accessed for this, and the filesystem is off of an EMC. The backup is triggered via CLI so we do have backups running during it (we just don't have a 6 hour window of downtime daily).
Any suggestions for improving the throughput rates would be appreciated. Thanks.
